theres a 4.51 :carling:
lol ok ok
and no there is no 4.oo cfw :carling: , theres just e3 flasher downgrade , but im worried this will stop the donwgrade or dual boot of e3 flasher
how seriously they would have to redesign the processor to block flashing of anything on the nor or nand to disallow it to be reflashed unless it had a certain hardware id

so they will never patch it easily on the ps3 it could be bypassed
